Unbelieveable..wonder how many E70s owners had a failed rear diff? It appears this is a common issue once it has reached the 100,000km mark.

Yes, the part itself is around $3,800AUD plus labour. $8k seems a bit excessive!! BMW Aust dealers don't normally stock any diff as it is not suppose to break and requires a special order via freight due to its sheer weight and size.
